DiCarlo: Through your pioneering work, you have developed a means of triggering non-ordinary states of reality in individuals. What might be the value in doing this?

Grof: Non-ordinary states of consciousness are certainly a unique source of deep insights into the deepest recesses of the human psyche. In my opinion their potential significance for psychiatry is comparable to the importance of the microscope for medicine or the telescope for astronomy. It is hard to believe that this area has been largely ignored by traditional psychiatrists and psychologists. I myself have been particularly interested in two aspects of non-ordinary states. First, it has been their extraordinary therapeutic or healing potential, naturally, if they are used properly and under supervision of an experienced guide. Since I am a clinical psychiatrist, this was my primary area of interest. Second, it has been their heuristic potential, that is, what we can learn in or through these states about the psyche, the unconscious, human nature, and the universe.

DiCarlo: In browsing through some professional psychological journals, I noticed that increasingly, some of the prevailing assumptions of traditional psychology are being called into question, such as "Psychological development largely ceases once biological adulthood is reached;" or "Psychological health is nothing more than not being sick;" and "transpersonal or mystical experiences are at best insignificant and at worst, signs of mental illness." As one of the principle architects of the emerging paradigm of psychology, what does your work suggest about the validity of these assumptions?

Grof: To your first point: Transpersonal psychology has amassed ample evidence suggesting that human psychological development can proceed far beyond a good interpersonal and social adjustment and adequate sexual functioning of a mature adult. The author who has written about this in the most articulate way is Ken Wilber. In his books, he offered an impressive and comprehensive synthesis of various schools of Western psychology and Eastern spiritual systems. He described in great detail additional stages of psychological development - the subtle, causal, and absolute. Since all these levels involve the spiritual dimension as a critical element, they require that spirituality be understood as a healthy and evolutionary manifestation, rather than an indication of lack of education or psychopathology.

As far as your second assumption is concerned: The attitude of Western psychiatry that sees mental health as simply the absence of symptoms certainly has to be radically revised. In the new understanding, emotional and psychosomatic symptoms are seen as expressions of the healing process of the organism, not as manifestations of disease. Obviously this applies only to "functional" or psychologically determined disorders and not to clearly organic conditions, such as tumors, infections, or hardening of the arteries of the brain. Nor would it apply in certain states which are clearly manifestations of mental disease, such as severe paranoid conditions. This new understanding can be described as "homeopathic". In the alternative system of medicine known as homeopathy, the symptoms are the seen as expressions of healing, not the disease. Therapy in homeopathy consists of a temporary intensification of the symptoms to achieve wholeness. This approach results in profound healing and positive personality transformation rather than the impoverishment of vitality and functioning that accompanies pharmacological suppression of symptoms. The emphasis on constructive working with symptoms instead of their routine suppression is the first major difference between the strategies based on modern consciousness research and those used in mainstream psychiatry.
